CEL-FI GO G41 Signal Booster for Home/Office with No Inside Signal

CEL-FI GO G41 Smart Signal Booster for Home & Office With No Inside Signal

The CEL-FI GO G41 Smart Signal Booster is a next-generation mobile signal booster for the UK, engineered to provide strong and reliable 3G, 4G, and 5G signal coverage in areas with little or no indoor signal. Designed to meet Ofcom standards, it delivers up to 100 dB of signal gain — offering unmatched voice clarity, high-speed data, and consistent mobile performance across all major UK networks including EE, Vodafone, O2, and Three.

Built with Nextivity’s advanced IntelliBoost technology, the CEL-FI GO G41 continuously monitors and optimises signal strength, ensuring maximum coverage and stability without interfering with other wireless devices. Its robust design makes it ideal for challenging indoor environments where traditional mobile reception is weak or non-existent.

The G41 provides reliable coverage of up to 1,500 m² with the included outdoor and indoor antennas. The system is scalable, meaning you can easily expand coverage by adding more indoor or outdoor antennas to meet the needs of larger homes, multi-storey offices, warehouses, agricultural sites, rural properties, and small manufacturing units.

Whether you need better mobile reception in a farmhouse, office block, or warehouse, the CEL-FI GO G41 mobile signal booster delivers a dependable connection where it’s needed most.

How It Works

The CEL-FI GO G41 works by capturing weak mobile signals from outside and boosting them indoors to eliminate dropped calls and poor data speeds:

1. An outdoor donor antenna is mounted outside your property to receive the best available mobile signal from the nearest cell tower.

2. The signal is transmitted to the CEL-FI GO G41 booster unit, which amplifies it intelligently and safely.

3. One or more indoor antennas then rebroadcast the enhanced signal throughout your home or office, ensuring strong, reliable coverage in every room.

This seamless system ensures that you can make clear voice calls, browse, and stream effortlessly — even in locations where indoor signal is normally too weak to connect.
